El Yunque Rainforest & Waterslide.

The Activity

A half-day in the canopy.

El Yunque is the only tropical rainforest in the United States forest system — 29,000 acres of cloud forest, switchback roads, and waterfalls fed by 200 inches of rain a year. The road in climbs out of the coastal plains and into a different climate within twenty minutes.

This particular tour keeps the group small (typically eight to twelve people), which means you actually get to talk to your guide. The route covers a moderate rainforest hike, two swimmable falls, and the natural rock waterslide that's been carved into the river by centuries of water — the same one locals have been sliding down since before the road existed.

Why people love it

Because every other version of this trip is on a bus with forty other people. You hike the same trails, swim in the same pools — but you do it with a guide who knows the names of the trees and isn't trying to corral a tour group. It's the difference between a postcard and a memory.

Why I love it

The waterslide. It looks intimidating from the top — a smooth groove of slick volcanic rock dropping into a green pool — and then the guide just walks up, sits down, and goes. After that, everyone else has to. It's the photo your group will be sending to their friends for years.

And the drive back: damp hair, sun coming through the windows, the smell of the rainforest still on your shirt. You'll be back at the house by mid-afternoon with the whole evening still ahead.
